Gauntlet offers a local coop for up to 4 players. It's not the best game I've played, but it was fun to play with friends.

Screencheat
Gunnheim

Check out those:

Brawlhalla (free)
Awesomenauts
Final exam
Sacred citadel
Bloody Trapland
Gang beasts

Rainbow Six: Vegas 2 - terrorist hunt mode.

Rocket League is good fun, even with just two. Just remember to choose the same team!

• Monaco
• Rayman Origins
• Lara Croft and the... (both games)
• Castle Crashers
• Hammerwatch
• Sonic & All-Stars Racing Transformed
• Shank
• LEGO (all of them)
• Trine
• Guacamelee!
• Nuclear Throne

If you have preferences of genre or setting please write them, I'll gladly try to help. :)

Try Towerfall as well, me and my friends love it!
Worms title are a little more slow-paced, but i have had so many giggles with it.
Also:
Mercenary Kings
Metal Slug

Gauntlet! Although I would much more recommend the Gamecube's Gauntlet; Dark Legacy.
Also Awesomenauts is a good game for this.
Basically, look up a ton of good multiplayer games for the Gamecube because those are the best.

Helldivers
Serious Sam BFE
Dungeon Defenders
Hyper Light Drifter
Fight the Dragon
F1 Race Stars
Kane & Lynch Dead Man
Double Dragon Neon
Renegade Ops
The Expendabros
Sacred Citadel
